E. C. Zeeman developed constructions in geometric topology. His paper on twist-spun knots studies higher-dimensional knots obtained by rotating a classical knot while adding twists.[ref]
Twisting spun knots by E. C. Zeeman. Original byline and introduction
The construction makes knot complements accessible through fiber bundles over a circle. A striking consequence is that the one-twist spin is unknotted, even when the original classical knot is nontrivial. The theorem connects an explicit motion of a diagram with the global topology of its complement.[ref]
